In a pregame ceremony, Metallica performed "Enter Sandman" to honor Mariano Rivera as he walked onto the field from the bullpen. Rivera's final regular-season game at Yankee Stadium will be Thursday, but the Yankees retired his number today.

The Yankees lost to the Giants, but Rivera did enter the game with one out and one on in the eighth. He struck out Ehire Adrianza and got Angel Pagan to fly out to end the inning before allowing just one single in a scoreless ninth.

Gothamist has a pretty good roundup of photos and fan videos from the pregame festivities. Check it out here.
